Something is wrong with the controls.

Every time I start up this game, I can't look around despite following the tutorial's instructions. I can't navigate through the control settings regularly with a mouse. i instead have to navigate through it with ARROW KEYS! WHICH IS THE MOST FRUSTRATING AS orc THING TO DO!

I can't "do" anything, and I'm just stuck there wondering why I'm trying. Does anyone else experience the same problem? And does anyone know how to fix this?
